Hoping someone here can lead me in the right direction. I'm having some issues with our family hauler 2013 URJ200 with 175K. We lost AHC system close to home luckily - limped back and plugged in techstream. Dreaded C1763 abnormal pump oil pressure showed up.
Here is the process I've gone through to diagnose/fix it:
- I hooked up 12 volts to the AHC pump in an attempt to jog it back to life with no movement.
- I inspected the fuses which all looked fine
- Discovered there is no AHC relay in the fuse box despite the cover showing their should be (see pictures below). Are all 2013s like this? Found a picture of a 2011 lx570 fusebox that had the same configuration as my fusebox cover. Anyone have a picture of their 2013 fusebox?
-Decided to install a new OEM AHC pump and globes. Original pump was heavily corroded (started life as a Maine truck) and globes were over 50K old. Poured a metal can's worth of fresh AHC fluid in the resevoir.
- Said a little prayer and started the truck - no pump motor movement and the C1763 returning immediately after clearing in TechStream.
I've read hear that sometimes a new AHC pump needs to be primed before the C1763 code clears. My though was to energize it 12V to get it started, but I also dont want to fry anything
Do you guys have any suggestions on getting the truck back in order?
Here are the current readouts from tech stream:
